To all lwhom t may concern:

Be it known that I, ANDY HOLDREN, a citizen of the United States,residing at Martins Ferry, in the county of Belmont and State of Ohio,have invented new and useful Improvements in Worm-Wrenches, of which thefollowing is a-s'pecification.

The present invention relates to improvements in wrenches, and has forits primary object to produce a wrench so constructed and arranged as topermit of the same to be used in corners or in inconvenient places notaccessible by an ordinary wrench.

The invention further consists in the construction, combination andoperative arrangement of parts set forth in the following descriptionand falling within the scope of the appended claim.

In the drawings,

Figure 1 is a perspective view of the wrench constructed in accordancewith the present invention.

Fig. 2 is a sectional view approximately on the line 2-2 of Fig. 1. Y

' Fig. 3 is a sectional view approximately on the line 3--3 of Fig. 2.

Fig. 4 is a perspective view of the toothed member carried by the headof the wrench.

Fig. 5 is a sectional view approximately on the line 5-5 of Fig. 4.

Fig. 6 is a perspective view of the shank designed to engage in the boreof the toothed member illustrated in Figs. 4 and 5.

Fig. 7 is a perspective view of one of the removable socket membersdesigned to engage with the shank.

Fig.A 8 is a perspective view of one of the elements comprising thehandle extension.

The wrench is broadly indicated by the numeral 10, the same including ahead 11 whichA is in the nature of a hollow casing and which has, what Iwill term, its sides 12 provided with alining openings forming bearingsfor the inner and rounded end of a handle member 13. The portion of thehandle'received in the lhead or casing 11 is provided with a worm screw14, and the outer end of the handle 13 is formed with a reduced roundextension 15 provided with 4a lateral lug 16. The extension 15 isdesigned to be received in the socket end 17 of a handle extensionmember 18, the sard member 18, at its outer end being provided ,with areduced extension, similar-to the' extension 15, and which isdesignatedby the numeral 19 and upon this reduced extension is formedone or more lugs 20. The socket end 17 of the member 18 is `providedwith a substantially T shaped .slot .21 entering from v the outer end ofthe said member 18, and this socket is designed to receive the lug 16,

and whereby, when the extension 18 is. turned a determined distance,upon thehandle 13,the lug will be seated against one` ofthe end wallsprovided bythe transverse opening in the` T shaped slot 21. Likewise thelug upon the extension 19 of the handle 20 is designed to be received ina Ti shaped slot in the socket end of a second extension, similar to themember 18 and in this manner, it will be noted that the handle may belengthened orshortened in accordance with the use of which the device isbeing applied to the convenience ofthe operator.

The walls of the head or casing `11 arranged at right angles totheportions 12 which I have termed the side's of the said casing areprovided with alined openings which are round and which are designed toreceivethe ends of a cylindrical member 22, the said'member, betweenthesaid walls of the casing, having its outer periphery formed with teeth23 which are engaged by the worm screw 14 of the handle 13, and byturning the said handle, the member 22 will likewise be turned but, ofcourse, at an angle with respect to the handle. vThe bore of thecylindrical member' 22 is provided with oppositely disposedylongitudinally extending slots 24, and the said bore, at the centerthereof is provided with transverse'depressions 25, each terminating anequal `distance ffrom the opposite sides of the slots 24, and

communicating with the said slots.

The shank 'of the wrench is indicated. by the numeral 26 and has one ofits ends rea size to be likewise received in the depressions 25 when theshank is turned pto bring the said lugs into the said depressions. .Itwill be noted, by reference to the drawings,

.that the reduced end of the shank'26 may enter the cylinder 22 fromeither. of the ends thereof, so that the wrench may be successfullyoperated` upon a nut or the like all."

ranged either above or below the said wrench, or as a matter of fact,.at any desired angle either above or below the said wrench.

rlFhe outer end of the shank 26 is provided with a socket 29 and islikewise provided with oppositel-y disposed 'l' shaped slots 30 whichenter from the end of the said socket, and, of course, communicate withthe socket.

rlhe nut or bolt holding member, or the socket proper is indicated bythe numeral 31, and is provided with a reduced stem 32, the said stembeing of a size to be snugly received in the socket 29 of the shank 2G,and upon the stein 32 is arranged diametrically pivotally disposed lugs33 that are adapted to be rst passed through the longitudinal passage ofthe T-shaped slot 230 and upon the turning of the socket member 3l withrespect to the shank 26, to enter the trans verse passages provided 'bythe said "l"- shaped slot and to contact with one of the end wallsprovided by the said transverse passages. p

From the foregoing description when taken in connection with thedrawings, it will be noted that my improved wrench may be successfullyemployed in corners or in other places where an ordinary wrench can notbe used. It is, of course, to be understood that a plurality of Shanks,similar to that illustrated may be connected together ina manner inwhich the socket 31 is connected with the shank 26, so that the lengthofthe shank may be readily regulated to accommodate the wrench tovarious classes of work. v

lt will be noted that the device is of a simple construction, and it isthought that from the foregoing the construction and ad- Maasai vantageswill be fully understood without further detailed description.

Having thus described the invention, what l claim is:

A wrench of the class set forth including a hollow substantiallyrectangular head having right angularly arranged alining openings, ahandle member journaled in two of said alining openings, a worm formedupon the handle and arranged in the head, said handle having its outerend reduced; a transverse pin on said reduced end, a handle extensionhaving a socket end provided with a. T shaped to be received in thecylindrical memberv and the lugs to be passed through the slots andenterl the depressions whenever the shank is turned upon the cylindricalmember, said shank having its outer end provided with an opening andfurther having a T shaped slot communicating with the opening, ay socketmember having a reducedveX- tension provided with lugs, and the said eX-tension designed to be received in the opening of the shank and the lugsthereof in the 'lV-shaped slots of the shank.
